What is WiFi?
In the modern day the internet has become something irreplaceable for us. But for us to access the internet we need WiFi or wireless network. Like radios the wireless network uses radio waves to transmit signals and it too has a transmitter and a receiver. These waves are able to travel back and forth.

How does WiFi work?
The computers' wireless adapter (a device that allows the connection between the modem and the device to be wireless) translates the information received into radio waves which is then distributed around the area through the antenna on the modem. Your choice of device is able to receive the radio waves given out after typing in the password. The radio waves received is then translated for the device to receive the information.

Modems
In our case of WiFi, the transmitter and receiver differ from radios in the way that the transmitter is the modem and the receiver is the device. The modem is what sends out radio waves through the antenna to your computer or laptop so that it is able to receive the information let out from wireless router. But in order for the modem to work and activate, a wireless router is necessary. Although the two look similar there uses are extremely different. The modem is what provides us internet from a cable that connects to a DSL and supplies us with internet. Whilst the router is what connects to the modem and is able to take signals from the modem and transmit them to other devices around the house, on top of that it is also what allows us to connect to the WiFi wirelessly.

What makes WiFi fast?
Sometimes our WiFi isn’t at top condition as it may be lagging, slow or not connecting properly. This may be due to interferences such as walls, although it will not completely stop the WiFi from working; it acts as some kind of obstruction. An example of this may be that a deer can run through heavy rain although this may be harder, the deer can still travel through the rain. In this specific case the deer would represent the radio waves let out from the modem.This shows that WiFi will slow down when there are obstructions such as walls. So if obstructions make WiFi slow what makes WiFi fast? Well although obstructions play a part of making WiFi slower the thing that makes the WiFi faster and better is a good wireless router.
